Hello,
Am using a Eheim Classic External Canister Filter. I have black spots and patches (algae or mulm?) that run along the whole of both the hoses/pipes connecting to the filter and the In/Out valve.
Any suggestions on how to clean them? I think brushes can only do so much, it cant reach the middle area. Any chemicals I can dip them in? I was thinking of bleach but am afraid it will corrode the plastic and also affect the fishes when I replug it into the aquarium..
I notice the the filter doesnt quite 'suck' as much as it used too. Im guessing its because of the black spots on the pipes/hoses and also because I extended the length of those pipes/hoses. Any other causes I should be aware of ?
Thanks..
